Macro partitioning
Replacing saturated fatty acids (SFA) with polyunsaturated fatty acids (PUFA), specifically linoleic acid (LA) found in seed oils, reduces cardiovascular disease (CVD) risk and is safe for long-term consumption.
Follow established dietary guidelines: limit saturated fats (like butter and lard) and replace them with unsaturated fats, including seed oils (like soybean, corn, or canola oil), to support heart health. The scientific consensus supports the safety and benefit of these oils.
it is concluded that data overwhelmingly support the safety and health benefits of seed oils and LA, not only with respect to CVD, but possibly other chronic diseases as well.
Why this rating
The paper cites large-scale observational studies, RCTs, and global burden of disease analyses.
